Is diarrhea really a symptom of MC?

Well I’ve had a terrible past couple of days worrying myself sick, but essentially up until 3 days ago, I was having terrible all day food aversions, nausea, etc. then it disappeared and completely started freaking myself out. Today, I’ve had nausea on and off, but also have had diarrhea (sorry TMI) and my lower back has been stiff and bothering me for days. I don’t have any cramping or bleeding, and almost felt better about feeling like crap because at least it means something. I stupidly went on google and found apparently diarrhea “can be” a sign of MC? Is that true? Anyone else have morning sickness in the form of 💩 issues and had a healthy pregnancy? I’m 6w5d
